I'm not sure how to run doom, but the point2Play proggie has a subscription fee, where they promised to
help get most modern games to run under linux, perhaps you could check their website
www.transgaming.net or som-ting.
if you have cedega try using that first, then according to to errors notices you get frrom running it
do a google search on them until you can get some solid to query user in here with.
I belive cedega /point2play can run doom3 and a load mo' windoze gaming s/ware.
the answer out there - also look for linux doom3 gamers/ forums etc until you can nail down
the precise problem
let me know what turns up.
ps: i have the windoize version of doom3, and i have read som' where that one could get an linux installer then copy your doom3.pak files 1-4 to a desired subdirectory and the linux installer will
use the pak files and allow you to use the game.
